First of all, may I sincerely apologise to all who replied for taking so long to update this thread. This was mainly due to ill health. I know and appreciate how frustrating it is when you reply to a query, never to hear from the person again, which was never my intention.
I really appreciate all the help I received, but I particularly would like to thank ukhardy07. Your help and support was invaluable. I would have given up after the first few attempts by BT to resolve the issue, but you encouraged me to persist.
I had a wonderful contact at BT, who worked with me to resolve the slow speed. After several engineer's visits, one found a damaged joint / cable and repaired it. I now also have BT Whole Home Wifi which is excellent. My speeds are now:-

Your Internet connection should be able to handle multiple devices streaming HD videos at the same time.
I cannot thank you enough.
I hope you have a lovely Christmas and New Year.
